Powering On the Unit
The Switch uses an AC power supply 100~240VAC, 50~60 Hz. The Switch’s power supply
automatically self-adjusts to the local power source and may be powered on without having any or
all LAN segment cables connected.
» Insert the power cable plug directly into the receptacle located at the front of the device.
» Plug the power adapter into an available socket.
Note: For international use, you may need to change the AC power adapter cord. You must use
a power cord set that has been approved for the receptacle type and electrical current in your
country.
» Check the front-panel LEDs as the device is powered on to verify that the Power LED is lit. If
not, check that the power cable is correctly and securely plugged in.
Installing the SFP modules and Fiber Cable
» Slide the selected SFP module into the selected SFP slot (Make sure the SFP module is aligned
correctly with the inside of the slot)
» Insert and slide the module into the SFP slot until it clicks into place
» Remove any rubber plugs that may be present in the SFP module’s mouth
» Align the fiber cable’s connector with the SFP module’s mouth and insert the connector
» Slide the connector in until a click is heard
» If you want to pull the connector out, first push down the release clip on top of the connector
to release the connector from the SFP module.
To properly connect fiber cabling: Check that the fiber terminators are clean. You can clean
the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted
through the cable and lead to degraded performance on the port.
Note: When inserting the cable, be sure the tab on the plug clicks into position to ensure that it is
properly seated.
Check the corresponding port LED on the Switch to be sure that the connection is valid. (Refer to
the LED chart).
